Quantity of coffee used per day by breakfast cafe =
[tex] = 3 \frac{1}{4} \: lb[/tex]
Quantity of coffee it will use in a seven day week =
[tex] = 3 \frac{1}{4} \times 7[/tex]
[tex] = \frac{(4 \times 3) + 1}{4} \times 7[/tex]
[tex] = \frac{13}{4} \times \frac{7}{1} [/tex]
[tex] = \frac{91}{4} [/tex]
[tex] = 22 \frac{3}{4} \: lb[/tex]
Therefore , a breakfast cafe will use =
[tex]22 \frac{3}{4} \: lb \: of \: coffee \: in \: a \: seven \: day \: week \: .[/tex]
